| 摘 要： | 桁架结构优化设计中普遍存在约束的作用.现有优化设计一般采用满应力法和遗传优化等优化方法,编程复杂.本文介绍了优化设计软件LINGO10.0的功能、特点、使用方法和使用注意事项等,建立了桁架结构优化设计的数学模型.采用LINGO软件的全局优化方法求解.实例计算表明,采用LINGO的全局优化方法能获得全局优化解,且方法简单,值得推广应用.

| Abstract: | The action of constraints exists in optimization design of truss structures.Usually,full stress method and genetic optimum method are adopted in optimization design of truss structure,and the programm is very complicated.The function characteristic,using method and item should be payed attention to of optimum design software LINGO10.0 were introduced.The mathematical model of truss structures,optimum design was built and solved by a global optimum method.The results show the model is practical and effective... |
